Timeline: What If We Drilled A Hole Through Earth

For the sake of our video, let's assume you could dig a wide and straight hole directly down to the center of earth until reaching the other side of earth. Further suppose the hole has a wall strong enough to keep it from collapsing or melting. Watch this timeline video to see how we proceed, what will be encountered and how can we take advantage of that?
